An investment thAt yields AccurAcy And profitCompanies that employ digital camera technology can rapidly increase their return on investment. Films, scanning, and processing account for the majority of the cost for typical photo flights using a film-based camera. With a digital camera, the laborious and time-consuming tasks of processing and scanning film are eliminated, resulting in significant savings in both time and money.

For a typical photo flight with a DMC to capture imagery of a city with an area of 890 square kilometers at a photo scale of 1:5000 with 60 percent overlap and 20 percent sidelap – an estimated total of 3,600 images – the DMC system can deliver savings of 50 to 75 percent of acquisition costs. This means companies can recover their investment very quickly. Return on investment for companies of varied ranges of image production will depend upon the size, type, and number of annual projects.

AccurAcy throuGh innovAtive desiGnThe DMC system was developed to bring the benefits of digital technology to aerial mapping cameras.

Exceeding the highest accuracy and rigid image geometry (repeatability), the DMC incorporates rigidly mounted frame sensors, giving stable internal geometry. Frame geometry is the preferred method for producing stable and reliable digital imagery. In addition, the new camera was designed to perform under diverse light conditions with a wide range of exposure times and utilizes electronic forward motion compensation (FMC).

chArGe coupled device (ccd) sensors record precise GeometryEmploying CCD frame (matrix) sensor technology allows the DMC to meet rigorous goals and offers advantages not seen with small-format framing sensor technology or line sensor technology. The technology ensures rigid image geometry in a fashion analogous to a precision film platen. The DMC is not dependent upon a global positioning system (GPS), if used. Even if GPS lock is completely lost, flight conditions are severely turbulent, or light conditions are poor, users can be assured that high-quality metric imagery is “in the can” and ready to exploit using traditional photogrammetric methods.

Features such as completely electronic FMC and 12-bit per pixel radiometric resolution for each of the panchromatic and color channels ensure image quality that is stunning compared to scanned aerial films. Because the DMC exposes a square pixel footprint and all camera heads are exposed simultaneously, the image is frozen in one shot and adverse influences due to airspeed fluctuation, sudden aircraft movement, or objects moving within the frame are minimized.

The CCDs are full-framed sensors with high optical fill factor and sensitivity. DMC offers pixel size of 12 microns by 12 microns (square) and with a high linear dynamic range of 12-bit. The architecture of the CCDs offers parallel readout registers on all four corners of the chip.

Because of the two-dimensional area sensor, the image data has a known and precise geometry in both X and Y directions. This provides a repetition rate for the system of one image every 2.1 seconds and high readout rates, which is important for a good signal-to-noise (S/N) ratio. The DMC ensures optimum precision results. For example, a photo flight at an altitude of 500 meters (1,640 feet) at an approximate speed of 140 knots produces images with 60 percent overlap in the flight direction and with a ground sampling distance of five centimeters (less than two inches).

innovAtive cAmerA, lens, And shutter technoloGyZ/I Imaging partnered with Carl Zeiss to develop a unique lens design, minimizing distortion and maximizing resolution. The DMC’s innovative design solves the problem of the size limitation of array CCDs by amalgamating eight individual CCD array cameras into a composite system. The DMC possesses a unique lens system, featuring minimal distortion, large (f/4) aperture, high resolution, and homogenous field response.

The eight individual camera modules are autonomous units and capture a central perspective view. Since separate lenses are used for each of the eight camera heads, the resulting overall image produces higher optical performance than can be achieved in a single, large-diameter lens. The high-resolution panchromatic channel contains four 7k x 4k large-area CCD chips and high-performance lenses with 120-millimeter focal length at a maximum aperture of f/4. For the simultaneous collection of color and false color infrared images, four multi-spectral camera heads are incorporated in the camera base unit.

To achieve high-quality color separation, each color channel features a separate high-performance, wide-

angle lens with a maximum aperture of f/4 and 25-millimeter focal length, a 3k x 2k CCD chip, and a high-performance color filter based on non-organic material. The cameras are mounted inside a rigid optics frame designed specifically to ensure precise alignment of the optical axes.

The front-end electronics, with signal conditioning, analog-to-digital conversion, CCD timing, and processing, are directly integrated inside the camera module. This integrated design technique ensures a very high S/N of the CCD and minimizes the electromagnetic interference (EMI) within the system. Shutter development was focused on achieving precise synchronization to exclude geometric errors. An electromechanical shutter placed in the center of each of the camera lenses exposes all image points through the optical paths at the same moment, resulting in a distortion-free image. The DMC shutters provide the operator superior performance over slit shutters used in standard reflex cameras by preventing geometric distortion inside the image field caused by aircraft movement during exposure time.

On top of the optics frame is the camera electronics unit. This enclosure houses the complete camera head electronics that control the camera modules, includes the power electronics for the shutters, collects the image data, and communicates with the camera

control unit. The camera control unit configures the complete system, communicates with the external systems, monitors the data flow, and stores data on solid state disks (SSD).

forwArd motion compensAtion (fmc)Electronic FMC is an absolute necessity for acquiring a blur-free image under large-scale mapping conditions. To allow fully electronic FMC of the digital image, the CCD matrix sensors used in the DMC camera heads are operated in time-delayed integration mode.

This technique is similar to the image blur removal concepts used in film cameras but without the limitation and potential failure modes of moving parts. The FMC used within the DMC is capable of compensating for much higher Velocity/Height (V/H) ratios than mechanical systems, thus greatly extending the operating envelope of the DMC. A large sensor area along the flight strip allows long exposure times while maintaining a high enough air speed for a photo flight with a fixed wing aircraft at low altitudes. This type of FMC cannot be achieved in standard linear CCD or “push broom” sensors. Electronic FMC, with the combination of precision optics and framing CCDs, allow the DMC to achieve high ground resolutions of only a few centimeters.

flexiBle on-BoArd systemTo ensure a smooth transition when replacing cameras in the aircraft, the DMC fits into the same form factors as existing film-based cameras, such as the RMK family of cameras, the LMK, or the RC camera series. This eliminates the need, in most cases, to modify the dimensions of an existing camera hole in the aircraft floor. The DMC also takes into account the maximum operational flexibility needed while transitioning to an all-digital configuration. Included as part of the system is Z/I Inflight, an integrated flight management system (FMS), which can also manage film-based cameras.

photo fliGht scope of ActionBesides adding flexibility for transitioning to a digital system, the Z/I Mount (the digital replacement for the industry-leading T-AS) Gyro Stabilized Suspension Mount compensates for the roll, pitch, and yaw of the aircraft. State-of-the-art digital microgyros, active control components, and passive vibration damping are used to stabilize the camera. Stabilization combined with improved vertical alignment of the camera ensures better image quality. The Z/I Mount is also compatible

with RMK-TOP film cameras and incorporates a digital interface for full control of the camera mount.

on-BoArd dAtA storAGe cApAcityWhen operated in full-color, 12-bit per pixel mode, the camera system generates about 272 megabytes of raw image data per exposure. Therefore, the control electronics require a special high-throughput design, which is capable of managing this data stream. It consists of two complete PCI-bus-based slot PCs operating in parallel. The image data of the camera modules is transferred via a parallel bus to high-speed, frame-grabber PCI-bus cards. Finally, the data is transferred via a separate data link from each of the CPU systems onto a removable, ruggedized storage system. This solid state disk system is a removable, solid-state RAM storage cartridge with a capacity of 1,200 images or 660 gigabytes. This high-speed, high-capacity solid state/storage is unique in the industry, providing unlimited storage with the use of multiple cartridges. These low-weight, compact units can be swapped out during the mission for unprecedented storage capacity and reliability. Since they are incorporated within the camera body itself, the space, weight, and power consumption

of disk drive units is completely eliminated. This allows the DMC system to be flown in an aircraft as small as a Cessna 206. Another important point to note is all previous DMC systems can be upgraded to SSD technology, again protecting our customers’ investment in Intergraph’s data acquisition solutions.

AccurAcy from stArt to finishThe DMC system provides a complete digital acquisition solution, including all of the hardware and software components necessary to address every stage of the workflow – from mission planning through post-processing.

comprehensive mission plAnninGSuccessful data acquisition starts with proper mission planning to set up and plan necessary flight lines to acquire imagery of target areas. The DMC utilizes newly designed software to implement and manage aerial surveys. Z/I Mission is a comprehensive mission planning, reporting, and post-processing tool that provides an innovative solution for aerial survey procedures – from creating the initial flight plans to generating reports and indices for the final exposures. Z/I Mission provides a rich data environment that can access vector mapping data, digital orthophotos, or any georeferenced raster backdrop, including KML or KMZ format of Google Earth. This mission planning system addresses usual functions such as flying a particular azimuth, planning the most economical mission for a given region of interest, 3D mission planning, and more. The geospatial software is an integrated system requiring no computer-aided design (CAD) or GIS software, and may be operated as a standalone product. It can incorporate CAD and GIS data in a seamless flight planning environment.

An added advantage is that Z/I Mission can utilize the data files from our previous flight planning software packages, thereby protecting our customers’ technology investment.

Z/I Mission includes 3D mission planning capabilities. This image shows the exposure centers at their precise position and the photo footprints projected onto the DTM surface exported into Google Earth.

inteGrAted sensors And in-fliGht feedBAckA tight coupling between the mission planning and photo flight operations, along with applications that perform automatic V/H and drift correction, eliminates the use of multiple tools and programs to convert and assemble the data for a photo flight and results in more efficient photo flights. The DMC system seamlessly integrates with Z/I Inflight to reach the highest possible level of automatic system control and monitoring of the camera. The FMS console gives the operator complete control of the DMC as well as an interface to all sensors within the airborne system. This includes the image acquisition sensors and the auxiliary sensors such as GPS, Gyro Stabilized Suspension Mount, inertial measurement unit (IMU), and more.

The flight management segment of the Z/I Inflight system manages the sensor environment during the actual data acquisition process of the photo flight. The DMC system moves this technology to the next generation by fully integrating the on-board systems and providing a modular architecture that allows the integration of additional sensors – multi-sensor platforms and ancillary mission support sensors, such as an optional IMU.

Z/I Inflight also incorporates a video camera to facilitate and enhance its ability to control and command attached sensors. The video camera is an intrinsic part of the base system and provides input for several functions. First, it serves as the input device to provide real-time feedback to the camera operator on the ground coverage of the sensor. The video frame-grabber can be synchronized with the sensor trigger to acquire a low-resolution video image of each image taken. A second function of the video images is to provide input to a computation algorithm within the sensor control that, combined with input from the GPS, performs a V/H computation used for FMC input for

the sensor. A third function of the video images is to provide input to the sensor control for a platform drift angle calculation. This calculation is used to drive the drift control of the stabilized Z/I Mount and to compensate the drift angle. As another option, if the system uses an optional IMU, measurements taken directly from the IMU can control the drift of the DMC.

Once the flight mission is planned, the information from the mission planning workstation is transferred to the FMS in preparation for photo flights via a USB memory stick. During the photo flight, Z/I Inflight records camera statistics, including video thumbnails, for analysis during the mission for post-mission review and processing. An optional IMU can be integrated directly inside the camera frame, minimizing the length of the lever arm for optimal coupling to the system and making it possible to work without ground control or with a reduced set of ground control points. Z/I Inflight can also control standard film-based cameras such as the RMK TOP systems, allowing quick interchanges between film-based and digital systems within the same aircraft using the same control interface.

rApid dAtA AccessUpon completion of the photo flight, the DMC provides a quick analysis of the success of the mission and enables a seamless flow of the acquired data into the digital workflow. Mission data is transferred from the on-board system directly onto the SSD, along with all other flight information. This eliminates the need for other media and keeps all flight data in one place for easy access and transfer.

During the photo flight, the operator can utilize the Airborne On-board Project Viewer (AOPV) to assemble the video thumbnails into a rough mosaic of the flight thus far to judge the quality of the imagery taken. For example, the operator can use the AOPV to view the images in detail while looking for cloud or cloud shadows. Imagery can then be immediately replaced as necessary by reflying at that time rather than at a later date, thereby saving significant time and money.

For missions involving multi-day remote operations, the latest Copy Station and Readout Station solutions provide extremely fast data copy from the SSDs. Copy Station is a mobile server with LCD display and keyboard in a rugged aluminum chassis. It contains 2 x 640 GB SATA disk arrays with a high-speed data interface, and can copy two of the previous generation FDS in about an hour. Copying 1,000 image FSD takes only about 40 minutes. Data post-processing in the field is also possible on this machine.

The Readout Station is a field copy device with built-in computer and SSD adaptor. It can copy to a variety of devices, including LT04 high-speed tape.

The true systems’ approach of the post-processing system design is evident through the immediate availability of the planning information in the overall data management of the production system. Mission reporting available in the Z/I Mission software automatically sets up the project information when the data is downloaded. Project management systems can be automatically populated with the actual mission data.

With Intergraph’s ImageStation Photogrammetric Manager, the planning information will automatically generate project information such as camera name, flight line IDs, photo IDs, photo center parameters, and more. This ensures a smooth, post-flight workflow. Planned data within the management system is updated with the actual mission parameters. For example, planned photo centers are updated to reflect true photo centers.

If the mission is output into TerraShare®, Intergraph’s automated data management system, as the actual images are introduced into the system, the data management system graphically indicates the status of the project through a symbolic representation. This allows the production manager to assign operators to the project in a phased manner.

simplified post-processinGOnce the images are acquired and the photo flight is complete, the imagery and actual mission parameters are downloaded from the SSD cartridge. The DMC post-processing system outputs images from the raw image data stored on the SSD. The ImageViewer software is used to preview actual post-flight image data, particularly for multi-day missions unable to return to home base.

Post-processing is completed in two steps: radiometric processing and geometric processing. Through the DMC post-processing software interface, the user enters parameters that specify the processing step options. First, the raw image data from the SSD is radiometrically processed to compensate for the effects of vignetting, aperture, and other radiometric factors. The intermediate images, generated from radiometric processing, are written to the RAID storage. Once this step is complete, the SSD may be removed and returned to the camera. The intermediate images are then geometrically corrected for lens distortion and tilt and combined by a mosaicking module.

The post-processing software can produce several different types of output files from the set of raw images stored on the SSD. These outputs include high resolution 7,680 x 13,824 panchromatic; color (RGB) and color infrared; and lower color resolution (2048 x 3072) outputs (color [RGB], color infrared, four band, and near infrared).

With even higher geometric accuracy and improved color (Brovey pan-sharpening) processing options, PPS produces the highest possible quality output data in high throughput data processing situations.

The output image data resulting from these processing steps can be transferred to a data management system, such as TerraShare, where it can be archived or distributed to the destination defined by the operator. Digital measurement in support of triangulation or input into an automatic triangulation process can proceed immediately rather than delaying the start of production until the entire project has been scanned.

dAtA AccurAcyImagery from the DMC is ready for the exploitation process within the end-to-end workflow. The accuracy of the data produced by the DMC enables a more automated process for downstream applications, thus resulting in faster throughput. After post-processing, imagery can immediately be brought into all stages of the photogrammetric workflow – aerotriangulation, feature collection, DTM generation, orthorectification, and more. Whether you employ the complete photogrammetry suite or third-party digital photogrammetry software, the DMC provides the imagery you need to meet the demands for small- or large-scale mapping at engineering-scale accuracy.

immediAtely AccessiBle AccurAcyThe adoption of a digital workflow for aerial photo flight missions results in the need to manage and store large quantities of image data. TerraShare makes this possible by streamlining and speeding the distribution and retrieval process with enterprise production management tools designed specifically for the earth imaging market.

TerraShare is Intergraph’s cost-effective, automated data management system. It provides accessible and secure long-term storage and management of digital imagery files, DTMs, vector data, and geospatial information in a work group or enterprise setting. The modular integrated design of TerraShare addresses geodata management and distribution needs within a single environment – regardless of the number of operational workflows that exist in the organization.

AccurAcy for mArket AdvAntAGeThe DMC system is capable of tackling the challenges of tough environmental conditions and the demands of daily project workloads and deadlines for multiple or large projects. With other systems, time of day and unfavorable weather conditions pose obstacles to achieving the best results in one flight. With high flexibility to allow recording of complete data by varying altitude and aircraft speed, the DMC ensures the maximum capture rate is achieved despite flight conditions. And with embedded technology to capture multispectral and panchromatic images in one flow, an on-board video image control can help identify environmental changes. Issues such as reflections and shadowing can be detected immediately so blocks or strips can be reshot during the same mission, avoiding landing and post-mission reflights.

In addition, the DMC offers a first, on-site quality check of acquired images without the delay associated with film processing, thereby helping to simplify logistics for out-bound missions and flights covering areas with restricted permissions. Designed to give flight companies a market advantage as they deliver extremely accurate data for imagery or as the basis for exploitation processes, the DMC vastly improves productivity in acquiring data by providing the following capabilities:
